HAND-CRANK.

Application filed September 21, 1916.

To all whom it may concern:

Be it known that I, VINCENT Annnn'r l/VALKUP, a citizen of the United States, residing at Apache, in the county of Caddo and State of Oklahoma, have invented new and useful Improvements in Hand-Cranks, of which the following is a specification.

This invention relates to a hand crank mechanism, and its object is to provide a crank handle for operating a shaft, the former being telescopically connected to the shaft so that it may be housed therein when not in use.

The device is designed more particularly for use in connection with a casket lowering apparatus, but it is not limited to such use and may be employed in connection with any other apparatus.

The object stated is attained by a novel combination and arrangement of parts to be hereinafter described and claimed, and in order that the invention may be better understood, reference is had to the accompanying drawing forming a part of this specification.

In the drawing- Figure 1 is an elevation of the device; Fig. 2 is a longitudinal section thereof, and Fig. 3 is a. longitudinal section showing the crank handle withdrawn in position for use.

Referring specifically to the drawing, 5 denotes a hollow shaft which may be employed for winding and unwinding a hoisting and lowering line.

The shaft 5 is rotatably mounted in a suitable support 6, and one end is shown provided with a closure in the form of a cap 7 provided with teeth 8 to form a ratchet wheel.

Specification of Letters Patent.

Patented Nov, 2?, ll t lu Serial No. 121,414.

The shaft is operated by a. crank handle 9 which is pivotally connected as shown at it) to a block 11 slidably mounted in the shaft 5, the pivotal connection being made with the outer end of the block. The shank of the crank is square in transverse section and passes through a square opening 12 in the center of the cap 7. When the crank 9 is swung into longitudinal alinement with the block 11 as shown in Fig. 2, said shank and block may be moved inwardly along t 1e shaft 5, and thus the major portion of the crank handle may be housed in the shaft. The shank of the crank may be pulled in an outward direction and swung at an angle to the shaft 5 as shown in Fig. 3, and when in this position the crank handle may be used manually for turning the shaft 5 in a 1nan ner which is apparent. The body portion of the block 11 is larger transversely than the opening 12, and consequently the cap 7 prevents the block and the crank handle from becoming detached from the shaft.

I claim The combination of a hollow shaft, a block slidably mounted in said shaft, a crank handle carried by the block and adapted to be projected from the end of the shaft, the shank of the crank being angular in crosssection and pivoted at its inner end to the block, and a fixed part on the shaft provided with an opening through which the crank shank passes, said opening corresponding to the cross-sectional shape of said shank, and the diameter of the block being greater than that of the opening.

In testimony whereof I a'flix my signature.

VINCENT ALBERT IVALKUP.
